摘要
目的 :了解公共场所空气质量对人体健康的影响 ,确保广大顾客和从业人员的身心健康。 方法 :对乌鲁木齐市 10家饭馆空气质量进行了调查及实验研究 ,各饭馆采用不同仪器和化学方法测定 SO2 、NOx、可吸入尘(IP)、空气细菌、平均等效声级、照度和微小气候。结果 :IP均超过公共场所饭馆 (餐厅 )国家卫生标准 (以下简称国家卫生标准 ) 2 .8～ 6 .8倍 ,各采样点和不同时间平均值之间均有显著性差异。平均等效声级均超过国家卫生标准 ,下午与晚上有显著性差异 (P <0 .0 5 ) ,但各采样点之间无显著性差异 (P >0 .0 5 )。 SO2 、NOx均低于国家卫生标准 ,但只有 SO2 下午和晚上测得的平均值之间有显著性差异 (P <0 .0 1)。空气细菌未超过国家卫生标准 ,不同时间和不同采样点测定平均值之间无显著性差异 (P >0 .0 5 )。微小气候中气湿超过国家卫生标准 ,不同时间测得的平均值之间有显著性差异 (P<0 .0 5 ) ,气温、气流、气压三项指标不同时间、不同采样点之间均无显著性差异 (P>0 .0 5 )。 结论
Objective: To explore the influenec of air quality in public place of dining room on body health in order to guarantee the health of wide people and customers. Methods: The concentrations of SO\-2, NOx, IP, number of air bacteria, noise, illuminate and microclimate were examined using different chemical methods and instruments. Results: The study showed that IP was significantly higher than the control group and it was 6.8 times as higher as hygienic standard of country for dining room. SO\-2, NOx were no statistically significant difference but there was difference of SO\-2 between AM and PM. Number of air bacteria had no difference between two groups and it was lower than those of hygienic standard of country for dining room. In the microclimate relative humidity was significantly higher than that of the control group, but others (temperature, humidity and wind speed) were no difference. Conclusion: Examination and hygienic supervision of air quality in public place are important for people and customer's health.
